What additives improve WPC’s resistance to mold in damp climates for Outdoor Rectangular Tables?

Wood-Plastic Composite (WPC) is a popular material for outdoor furniture, including rectangular tables, due to its durability and low maintenance. However, in damp climates, WPC can be susceptible to mold growth, which compromises its appearance and longevity. To address this issue, certain additives can be incorporated into WPC formulations to enhance its resistance to mold.

1. Biocides: Biocides are chemical additives that inhibit the growth of mold and other microorganisms. They are highly effective in preventing mold formation on WPC surfaces, especially in humid environments.

2. Zinc Borate: This additive acts as both a fungicide and a fire retardant. It provides long-term protection against mold and mildew, making it ideal for outdoor WPC tables exposed to moisture.

3. Calcium Stearate: Often used as a lubricant in WPC production, calcium stearate also repels water, reducing the material's susceptibility to mold growth.

4. Nano-Silver Particles: These particles have antimicrobial properties that prevent mold and bacterial growth. They are increasingly used in WPC for outdoor applications.

5. UV Stabilizers: While primarily used to protect WPC from sun damage, UV stabilizers also help maintain the material's integrity, indirectly reducing the risk of mold by preventing surface degradation.

By incorporating these additives, manufacturers can significantly improve the mold resistance of WPC outdoor rectangular tables, ensuring they remain durable and visually appealing even in damp climates.
